b6489ac066 test-coroutine: Add rwlock downgrade test
Test that downgrading an rwlock does not result in a failure to
schedule coroutines queued on the rwlock.

The diagram associated with test_co_rwlock_downgrade() describes the
intended behaviour, but what was observed previously corresponds to:

6162f7dafe utils: Work around mingw strto*l bug with 0x
Mingw recognizes that "0x" has value 0 without setting errno, but
fails to advance endptr to the trailing garbage 'x'.  This in turn
showed up in our recent testsuite additions for qemu_strtosz (commit
1657ba44b4 utils: Enhance testsuite for do_strtosz()); adjust our
remaining tests to show that we now work around this windows bug.

This patch intentionally fails check-syntax for use of strtol.

061d79097c utils: Tighter tests for qemu_strtosz
Our tests were not validating the return value in all cases, nor was
it guaranteeing our documented claim that 'res' is unchanged on error.
For that matter, it wasn't as thorough as the existing tests for
qemu_strtoi() and friends for proving that endptr and res are sanely
set.  Enhancing the test found one case where we violated our
documentation: namely, when failing with EINVAL when endptr is NULL,
we shouldn't modify res.

6e2e12a70c tests-qmp-cmds: Drop unused and incorrect qmp_TestIfCmd()
Commit 967c885108 "qapi: add 'if' to top-level expressions" added
command TestIfCmd with an 'if' condition.  It also added the
qmp_TestIfCmd() to go with it, guarded by the corresponding #if.
Commit ccadd6bcba "qapi: Add 'if' to implicit struct members" changed
the command, but not the function.  Compiles only because we don't
satisfy the #if.  Instead of fixing the function, simply drop it.

d8b2e5639a tests/unit/test-block-iothread: fix maybe-uninitialized error on GCC 11
When building qemu with GCC 11, test-block-iothread produces the following
warning:

../tests/unit/test-block-iothread.c:148:11: error: ‘buf’ may be used
uninitialized [-Werror=maybe-uninitialized]

This is caused by buf[512] left uninitialized and passed to
bdrv_save_vmstate() that expects a const uint8_t *, so the compiler
assumes it will be read and expects the parameter to be initialized.
